IFB
IFB
serves as a voice cueing mechanism for on-air talent. The talent listens to a program audio signal which can be interrupted
by the voice of a production person (such as a director or producer) for the purpose of giving instructions to the talent
regarding the show in progress.
Once IFB is configured (refer to the VLink/VLinkLE System Administration Application User Guide for detail instruction on
configuring IFB), click on your IFB key to establish a line of communication with the receiving user. The button will be set to
momentary only
so the IFB function remains active only while the key is pressed. All other active listen channels of the
receiving user are temporarily muted or dimmed until the sender releases the IFB key. Upon release of the key, normal
operation is restored. All control keys programmed to operate the same IFB output flash to indicate the function is in use.
ISO
ISO
is an intercom function by which a temporary and private communication link is established between an operator who is
located at an intercom control panel and another operator. The function is valuable wherever a short term private exchange is
required between two (2) operators who are normally sharing the conversation required to accomplish a group activity. The
most common use for this function is in television production for camera and video operators. The function also is found in
military and commercial systems.
Once ISO is configured (refer to the VLink/VLinkLE System Administration Application User Guide for detail instruction on
configuring ISO), click the ISO key to establish a private line of communication with the programmed destination station or
port. Pressing the key again releases the ISO function and the system returns to normal operation. While the function is in use
keys that are programmed on multiple panels for the same destination flash to indicate the function is in use.
Interfacing with other Systems
VLink/VLinkLE interfaces with 2-way radios, hardware-based communications systems, and public/private telephone
networks. These channels are typically designated to reflect such and may be talk only (such as paging) or talk/listen. They
can be set up as Point-to-Points, Group Calls, or Party Lines depending on functional requirements. For use with a 2-way
radio, clicking on the talk key initiates the transmit function.
